Adjectives can name the qualities in various levels of gradation (stopniowanie): such as it is hot, but yesterday it was hotter. Yet, tomorrow is supposed to be the hottest day.As in the example there are three levels of the gradation, the so called “równy stopień” (the first level, the adjective’s main form), “wyższy” (higher) and “najwyższy” (the highest) levels.

In Polish language (just like in English) you have two ways of making the gradation - Simple and Descriptive Ways (stopniowanie proste i opisowe).

Stopniowanie proste:​I level: adjectiveII level: adjective +-szy endingIII level:naj-+ II levelWysoki – wyższy – najwyższyWesoły – weselszy – najweselszy(Note: there are many changes in the stem of adjectives in the II level, you will have to pay attention to this changes, try to remember them)
